The Bocks of Vitilevu , Fiji . 
Prelininary Report b.y 
A, A. Pegau 
The igneous rocks include many types; granite, diorite, 
gabbro, diabase, andesite, basalt, basaltic glass, rhyolite, 
and tuff. 
The sedimentary types are limited and include chiefly 
limestone, shaly limestone, and sediments made up of fragments 
of igneous rocks, chiefly basalt and basaltic glass, cemented 
with calcite. 
There are no highly metamorphosed rocks although some of 
the igneous types show slight metamorphism, as manifested by 
undulatcry extinction in quartz, crushing and recement*a tion 
of the feldspars, and parallel orientation of the other 
minerals. Some of the limestones show a foliation and the 
rock breaks off in slabs. The calcite shows crushing and 
recrystallization. These rocks were collected from localities 
where previous workers had reported highly metamorphosed 
rocks .
